OK I understand better now The only thing is that when i screw in the idle fully and apply the break (this was prior to putting my break linkage in the correct position) the slide still closed fully, stalling the engine. So the screw still allowed this to close. What do you think would cause this problem?
So a different but not unrelated question; when people show videos of them loosening and/or tightening their idle screw which allows their carb slider to move, this is because their servo and linkage is set to so the slider is 'pushing' against the stopper? In other words, the linkage/springs should be as tight as possible?
Thanks very much for your help I really appreciate it, I'm still new but love to learn!
